A King and No King is a Jacobean era stage play, a tragicomedy written by Francis Beaumont and John Fletcher and first published in 1619. It has traditionally been among the most highly praised and popular works in the canon of Fletcher and his collaborators. The play's title became almost proverbial by the middle of the 17th century, and was used repeatedly in the polemical literature of the mid-century political crisis to refer to the problem and predicament of King Charles I.
